Caladium plant named ‘Clowning Around’

ABSTRACT

A new and distinct cultivar of Caladium plant named ‘Clowning Around’, characterized by its intermediate to tall height; upright and mounding plant habit; dense and bushy appearance; vigorous growth habit and rapid growth rate; fancy-type leaves that have dark green-colored margins with greyed red, greyed purple and red-colored centers with random dark green-colored spots and blotches; and leaf petioles that are medium green flushed with greyed red in color with dark greenish brown-colored stippling, streaks and tessellations.

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘CLOWNING AROUND’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium X hortulanum, commercially referred to as a fancy leaf-type Caladium and hereinafter referred to by the name ‘Clowning Around’.

The objective of the Inventor's breeding program is to create new Caladium plants that have uniform plant habit, exceptional container and garden performance and attractive and unique leaf coloration.

The new Caladium plant originated from a cross-pollination made by the Inventor in April, 2012 in Avon Park, Fla. of Caladium X hortulanum ‘Red Flash’, not patented, as the female, or seed, parent with Caladium X hortulanum ‘Twist N' Shout’, not patented, as the male, or pollen, parent. The new Caladium plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Zolfo Springs, Fla. in September, 2013.

Asexual reproduction of the new Caladium plant by “chipping” the tubers (cutting the tuber into segments with each segment containing an axillary bud and tuber cortical tissue) in a controlled outdoor nursery environment in Zolfo Springs, Fla. since April, 2014 has shown that the unique features of this new Caladium plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Caladium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Clowning Around’. These characteristics in combination distinguish ‘Clowning Around’ as a new and distinct Caladium plant:

-   -   1. Intermediate to tall in height and upright and mounding plant         habit; dense and bushy appearance.     -   2. Vigorous growth habit and rapid growth rate.     -   3. Fancy-type leaves that have dark green-colored margins with         greyed red, greyed purple and red-colored centers with random         dark green-colored spots and blotches.     -   4. Petioles that are medium green flushed with greyed red in         color with dark greenish brown-colored stippling, streaks and         tessellations.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Red Flash’, in the following characteristics:

-   -   1. Plants of the new Caladium grow much faster than plants of         ‘Red Flash’.     -   2. Plants of the new Caladium and ‘Red Flash’ differ in leaf         color as leaves of plants of the new Caladium have dark         green-colored margins with greyed red, greyed purple and         red-colored centers with random dark green-colored spots and         blotches whereas leaves of plants of ‘Red Flash’ have         red-colored venation and interveinal areas with pink and         white-colored spots and dark green-colored borders.

Plants of the new Caladium differ primarily from plants of the male parent, ‘Twist N' Shout’, in leaf color as leaves of plants of the new Caladium have dark green-colored margins with greyed red, greyed purple and red-colored centers with random dark green-colored spots and blotches whereas leaves of plants of ‘Twist N' Shout’ are olive green in color with green to coppery bronze-colored venation and coppery orange-colored spots and blotches.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Creamsickle’, disclosed in U.S. Plant Pat. No. 23,991. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Creamsickle’ in leaf color as leaves of plants of the new Caladium have dark green-colored margins with greyed red, greyed purple and red-colored centers with random dark green-colored spots and blotches whereas leaves of plants of ‘Creamsickle’ have greyed green-colored venation, greyed green and greyed purple-colored interveinal areas interspersed with dark green-colored sectors and borders.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Mesmerized’, disclosed in U.S. Plant Pat. No. 29,545. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Mesmerized’ in leaf color as leaves of plants of the new Caladium have dark green-colored margins with greyed red, greyed purple and red-colored centers with random dark green-colored spots and blotches whereas leaves of plants of ‘Mesmerized’ are variegated with variable areas that are dark green, red orange, whitish green and white in color; with development, mature leaves are mostly dark green in color with variable areas of variegation and interveinal areas with variably coalescing red orange-colored spots and splotches.

The accompanying photographs illustrate the overall appearance of the new Caladium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium plant.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in a polypropylene-covered shadehouse (30% light reduction) in Avon Park, Fla. and plants grown in ground beds under full sunlight conditions in an outdoor nursery in Crewsville, Fla. The plants were grown under cultural practices typical of commercial shadehouse and outdoor nursery production. During the production of the shadehouse-grown plants, day temperatures ranged from about 28° C. to 33° C., night temperatures ranged from about 22° C. to 25° C. and light levels were about 8,000 foot-candles. During the production of the outdoor nursery-grown plants, day temperatures ranged from about 29° C. to 35° C., night temperatures ranged from about 23° C. to 26° C. and light levels ranged from 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were eight weeks old and plants grown in the outdoor nursery were seven months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
